Fig. l is a side elevation of a well-known type of household vacuum cleaner having the invention incorporated therein; g.. 2 is a iront 'View of a portion of handle showing the sneed switch and its supporting plate; il is a side View of a portion o' the hariiclle showing tooth switches; and lig., is a iront vletv the plate which supports the switch.

xThe handle 6, as si in E, form of a cyliifitirical, nieta" tttie, and formed oecut a rectangulaio oneni ,j i Wall for the reception of snee enti a similar hut somewhat larger o ei 3@ rear Wall foi' the main switch lll.

The plate or mounting tot supp .stain switch is indicated a'. i6, and is prei s .i out of sheet met-al, seing matie to fit the tubular handle 6. n om the mounting of the switch meot plate, the latter is provided vJi central 'flat ioo'tion l? having the hol which passes the hollow steil 2li "i outer surface to receive the elu g s@ which rigidly secures the switch structure `,importing plate lo, a projection oi hey 23 top oi the hole 18 entering a groove iev wat the stucl 2o and preventing the tutele@ of tie latter when the clamping not is tightei l5 rlhe means for secui'ing the lower enel o plate le to the handle comprise the hf gwsunnottu ing hook 26 with its shanl; 27 nositionea to oveille the outer surface oi the handle 5 tlie lower M entemity of the opening, and the eioninwaitlly D@ offset lugs or ingers 28 to underlie the inner sur face oi the handle. Thus the loweir extremity oi plate 16 grips the Wall o the handle on 'both inside and outside and holds the end of the plate securely in position.

The upper end of the plate is fiztecl to the han- Serial No. 453,843

elle by the sheet metal screw 30 which passes through the hole 32 formed near the ton margin of the plate 16 and through the metal Wall. of the handle, a small hole nest being formed in the handle to start the screw which will cut its own thread. A lock Washer is provided. beneath the head ofthe screw to prevent loosening.

The method of assembling the plate ith its switch lli in position on or in the handle is as follows: The handle and the switch hailing ate been Wired, the switch is secured to the switch body is next passetl in the handle into the im'teifioi1 slate hroughtagainst and. its supporting plate "zo upward until the lugs or edge of the opennff. The lower ff is not? pushed inofaifdly the lingers 23 beneath the wall of the shank 27 oi the hooi: alcove the s mounting 6 tot the in jection or lip is nrovlaecl extenoing ly lowei" portion of the 'plate s rounding an onenng 35 therein. The eiectiic cord entete the hanclie through ois openHI ring, heling supported hy the encirclin inner enclos? which is beneath the lon-f gituclinal raised rio 3l.

The plate 34 which snppoits the sneed switch is siinilar in construction the plate wh supports the main switch. instead, however, of the hooli it has a rnidclle lug also lachs the hole anti annular loess for the electric corel.. The .nietlmel of assembling both switches is `lhe seine.

Owing to the depression ei the r ll of the the body of the stvi'lcli onset sot' what as shown at 33 the portion the plate le, thus permitting the unser N the switch ioocly to pass undef the Wall the handle when the parts are pushed upwardly in the assembling operation.

The present invention allords a simple, ineam pensive, and efficient method of mounting electrical switches or other attachments upon .the tubular handles of vacuum cleaners or other an" paratlls.. l; is only necessaria to out the open rin! in the handle and bore one small hole.

Since the plate covers the top and side margins of the opening, care need be taken in finishing only the bottom margin. But a single screw is required, yetthe parts are held most securely in position. The plate is of a shape and construction that can be produced at a minimum of cost for material and labor, and assembling is easily and lquickly accomplished.

Having thus described the invention, what is claimed is:

1. The combination with a handle having a tubular wall with an opening therein, said opening, at one of its ends, being shaped to have marginal edge portions angularly arranged with respect to each other, of a plate having a cylindrical contour to conform to the handle, the plate having side portions extending beyond the edges of the opening and lying closely against the ex terior of the tubular wall, ai; inwardly lient lng at one end o! the plate to he in i ted into the opening to engage the interior oi' vall to prevent outw ward movement oi' the ond ol plate and 'to engage in the angle formed ily said portionzf: to prevent lateral displacement, and detachable means passing through the other end of the plate and the wall to secure said and to the handle.

2. The combination with a handle havingA a tubular wall with an opening therein, said opening, at one of its ends, being shaped to have marginal edge portions angularly arranged with respect to each other of a plate having a cylindrical contour to conform to the handle. the plate having side portions extending beyond the edges of the opening and lying closely against the exterior of the tubular wall, the plate having lugs at one end to engage respectively the inner and outer surfaces of said wall, the lug which engages the inner surface of the wall also engaging in the angle formed by said edge portions to prevent lateral displacement of the plate and means passing through the other end of the plate and the wall to secure said end to the handle.

3. The combination with a handle having a tubular wall with an opening therein, oi a plate having a cylindrical contour to conform to the handle, the plate having side portions extending beyond the edges of the opening and lying close ly against the exterior of the tubular Wall, the pate having lugs at one end to engage respeotlvely the :inner and outer surfaces of .said wall, the exterior lug being downwardly extended and uw 'wardly curved to form a supporting hook, and means passing through the other end o! the plate and the wall to secure said end to the handle.
